Investors continued selling Twitter Inc (NYSE: TWTR) Friday as shares were lower by more than 5 percent just one day after plunging more than 10 percent.

Investors were clearly displeased with Twitter's fourth quarter report and alarming guidance, which calls into question if the social media company can turn itself around.

Twitter's turnaround story might be more difficult than expected as the earnings report revealed just how poor its user base is. As noted by Statista, Twitter's user growth slowed down "significantly" after it breached the 300 million user base milestone.

Statista noted Twitter gained a mere 31 million active users over the past two years, which is "disappointing" for a company that wants to become the global platform to exchange ideas and information.

Statista added that Twitter's user base is even more disappointing when compared to its peers. For example, Facebook Inc (NASDAQ: FB)'s WhatsApp, Messenger and core-Facebook platform each gained more users over the past two years than Twitter has in total.

Snapchat also added nearly three times as many daily active users as Twitter did monthly active users going back to the end of 2014. This isn't an apples-to-apples comparison, but it's a way to show how Twitter lags all of its social media peers.
